Application filed April 5, 1915. Serial No. 19,390.

To all whom it may concern Be it known that 1, JOHN E. CHRISTIE, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and useful. Improvement in Circuit-Closing Combination Alarm-Locks, of which the following is a specification.

My invention relates to improvements in :ircuit closing combination alarm looks that can be used on automobiles, doors, gates and the like.

One object of my invention is to provide a. circuit closing combination alarm lock that will give an alarm when any one of the wrong combinations has been moved.

Another object of my invention is to provide a circuit-closing combination alarm lock that will prevent an unauthorized person from operating it, or tampering with it in any way, without the alarm sounding, unless they have the right combination.

Another object of my invention is to provide a circuit-closing combination alarm lock that will prevent the electric current being turned on by a person who has not the knowledge of the right combination.

Another object of my invention is to provide a circuit-closing combination alarm lock that will give alarm by closing the circuit with the electric alarm bell when the hood of the gas engine on the automobile is opened by any unauthorized person.

Similar letters and numerals refer to like parts through the several views.

A denotes the section of a dash board of an automobile to which a casing E and a cover B surrounding the same are secured. The cover B is provided with an interior chamber D by a plate 7 3 which extends parallel to the front plate of the cover the entire Width thereof but stops short of the ends thereof in the longitudinal direction. Transverse plates at the ends of plate 73 space it from the cover and screws 7 1 hold the parts together.

The casing E comprises the end walls 27 and the bridge 27 integral therewith. The bridge 27 contains a plurality of openings l12 to permit insertion of push buttons 112 which at their inner ends carry combination locking tumblers respectively denoted 112. These tumblers are recessed to contain notches 65 and 66 and grooves 66. The openings l12 of the casing extend to the bottom thereof through the different parts assembled therein in order to receive the locking tumblers and springs 52 acting on their inner ends to hold them normally in inoperative position. Additional push buttons 1318 are also provided which serve for the operation of switches 19, 20 and 21 controlling the circuits for the tail and head lights and are mounted in the easing E. The cover B is provided with locking lugs 22 and 23 which enter suitable openings 22 and 23 in the casing E and its appertaining parts. The locking lugs are equipped with holding notches 22 and 23 in which parts of a main circuit closing switch enter, whereby the cover B is locked to the casing E and to the dash board of the automobile. An insulating plate 51 is socured in any suitable or appropriate manner to the dash board A. and to this plate a back filling plate 25 is secured such as by means of the threaded members 70. A main circuit closing switch 26, to which reference will be made hereinafter, is placed in front of the back filling plate. The front filling plate it has sliding engagement with the switch and extends the entire length of the casing E.

The main circuit closing switch 26 is adapted to be reciprocated between the back and front filling plates and 2t and comprises, as is obvious from t) and 10, a center plate 28 which is provided with a pl urality of lugs 30, 31 and 32, whereby a plurality of notches is formed. The center plate 2% is formed integral with side plates which are provided with ratched notches 2 for a purpose hereinafter stated. The closing switch 26 is provided at one of its ends with a head 32 which is secured to the neck 3t of the switch by providing an insulation 33 on the neck. The neck 34: is formed with a reduced extension 34- having threads whereby the head 32 may be detachably secured to the main circuit closing switch. The switch 26 is controlled by a spring 36 surrounding a cylindrical extension of the switch and held in place by a sleeve 2-37 which is secured by means of a bracket to the side wall 2? of the casing E. in alarm circuit is provided having ter miuals 33 mounted on the insulating basis 51. The wires of this circuit lead to the automobile hood or cover of the gas engine where an electric hell or a similar audible signal is provided. The main circuit adapted to be closed by the switch 26 has terminals 39 in proximity to the terminals 38 with which the head 32 is adapted to contact. The alarm circuit is formed in the interior of the casing E by the front plates t0 and ll arranged above and below the main circuit switch 26 and the back metal plates t2 and which are in horizontal alinement with the respective tront plates, but spaced therefrom. The plates i0, 41, s2 and l?) are connected upon manipulation of certain push buttons by the alarm circuit closing keys it which are formed integral with the part adapted to engage the ratched notches Q9 of the switch 26. The space between the front metal plates i0 and t1 and the back metal plates 42 and 43 is l'CSPQCtlVClV denoted by (37 and 67. From the back metal plates 42 and wires 16 lead to the terminals 63 and (it of the alarm circuit. In the casing E the top uide plate it? and the bottom guide plate it are provided. A center insulating plate t8 is arranged between the guide plate 47 and the metal top plates l0 and 4-2, while the insulating plate 50 is secured to the insulating plate 51 whereby the closing keys et are insulated from the cover B. A bottom insulating plate 1:!) is arranged underneath the plates t1 and -13. With reference to Fig. 12 it is seen that wires and are connected to terminals 5 3 and 19 of the switch 19 which may be actuated by the push buttons 17 and 18. The wires lead to the tail lights of the automobile and upon proper manipulation of the push rods the circuit for these lights may be closed. The headlights are simultaneously arranged in a circuit, whose wires 55 and 56 are connected with the middle studs of the switches 20 and 21. Terminals 58, 59 and 59 are provided in operative relation to the switches 20, 21. and the terminals 58 and 59 are connected by a low resistance wire 57 while a high resistance wire ()0 interconnects the terminals 59 and 59. From the drawing it is obvious that according to the position of the switches 20 and 20 a circuit between the wires and 56 may be closed through the wire 57 of comparatively little resistance, or through the wire (30 of high resistance. so that when desired the headlights may be dimmed. The various wires leading to the switches for the lights are threaded through openings (31, (51, (32 and G2 in the back insulating plate 51.

The top guide plate l7 and the bottom guide plate t? are provided with slots (38 in order to permit the insertion of the lock iug keys it. Similarly the center insulating plate 48 and the front metal plate l-0 are notched whereby the alarm circuit may be closed by means of the locking keys 44-.

In assembling the various parts of the device the back insulating plate 51 is secured to the back filling plate 25 by means of screws 70. shown in Fig. 2. The end plates 27 integral with the bridge 27 are secured to the back filling plate 25 by means of screws 71 (Fig. 1(3). The main circuit closing switch 26 is placed in front of the back filling plate 25 which maybe freely moved in View of an opening being cut in one of the ends 27. as shown at 72 in Fig. 13. The front filling plate Q-l is then placed in front of the main circuit closing switch 26 and between the side walls 27, and is secured thereto by means of screws 73. The springs on the combination locking tumblers i to lOO 12 are then placed into the openings 1 to 12, whereupoi'i the top guide plate 4 7, the center insulating plate l8, the back metal plate 4-2 and the front metal plate 40 are mounted in place and secured together by means of screws. The last mentioned plates are, of course, arranged between the end plate 27 and the casing E. The parts being secured in place, the notches GS of the plates register so that the circuit closing keys H may be introduced to close the alarm circuit when the push buttons are wrongly applied, as hereinafter further specified. Spacing strips 76 are inserted at both ends of the plate to space the insulating plate 50 from the alarm circuit plates and 42. The bottom insulating plate 49, the front metal plate 41 and the back metal plate 43 are then secured together and placed between the end plates 27 where they are fastened by means of screws 78. The metal plates 41, 43 are separated from the bottom guide plate by spacing strips 76. The light switches 19, 20 and 21 are then mounted on the bottom insulating plate 49 by means of screws forming the terminals 19, 20, and 21 whereupon the combination casing E is completed. Terminals 38, 39 of the main circuit and terminals 63 and 64 of the alarm circuit are subsequently provided on the back insulating plate 51, and the spring 36 surrounding the back lug 35 of the switch 26 is placed in po sition and the bracket 37 forming the casing for the spring 36 is secured to the end 27 by means of a screw 79.

To construct the cover B the push buttons are placed in the openings of the front plate, as indicated in Fig. 1. Subsequently the springs 69 are threaded on the push buttons 112. The plate 73 is then provided with the locking lugs 22 and 23 which serve for holding the cover B unto the combination casing E, and is secured to the transverse parallel plates of the cover B by means of screws 74 whereby the chamber D is formed wherein the various springs 69 of the push buttons 112 are incased. Finally the push button C is secured at one side of the cover B by means of the washer 80, whereupon the cover B is ready for being placed unto the combination casing E.

To mount the cover B it is necessary to actuate several push buttons forming the combination of the lock which, in the present instance, are the push buttons 2, 8, 10, and 11, carrying the combination locking tumblers 2, 8, 10, and 11, whereupon the notches of the aforementioned locking tumblers are in such a position as to permit movement of the main circuit closing switch 26 so that the lugs 30 of the switch pass out of the holes 22 and 23, so that the lugs 22 and 23 may enter the holes 22 and 23 adapted to receive them, and the cover B may then be passed over the back insulating plat 51. Having secured the cover B in place, the push button C is pushed in so that the circuit closing switch is placed in its former position in which the lugs 30 will enter the notches 22" and 23 of the lugs 22 and 23, thus preventing the cover from being removed until the right combination of push buttons is actuated. In order to hold the cover B rigidly the same may be secured to the back insulating plates 51 by means of screws 81in addition to the locking means.

In case the light switches are to be used, such as is necessary when the invention is ap plied to an automobile,the cover B is taken off by removing the screws 81 and operating the right combination as indicated above, so that the main circuit closing switch can travel in the direction of the arrow, and the lugs 30 pass out of the holes 22 and 23 and out of the notches 22 and 23, thus permitting the withdrawal of the locking lugs 22 and 23 and incidentally of the cover B. Then the wires 53, 54, 55, 56, 57, and 60, are arranged in their relative positions and the wires 53, 54, 55,and 56, are threaded through the openings 61, 61, 62, and 62, in the back insulating plate 51 and the dash board A. Thereupon the cover is secured in place, as hereinbefore described.

In the operation of the switches for the lights the push button 18 is actuated when it is desired to turn on the tail lights, so that the switch 19 is brought into contact with the terminals 53 and a circuit is established through wire 53, terminal 53, switch 19 and return wire 54. The terminal 59 is connected by the wire 57 to the terminal 58 at one side of the switch 20 or by the wire 60 of high resistance to the terminal 59 on the other side of the switch 20. By actuating the push button 14 the circuit is established through the wires 55, terminal 20, switch 20, terminal 58, low resistance Wire 57, terminal 59, switch 21, terminal 21 and return wire 56. In case, however, that the head lights are to be dimmed the push button 16 is actuated in addition to push button 14, whereby the circuit is established in the following manner: wire 55, terminal 20, switch 20, terminal 59, high resistance wire 60, terminal 59, switch 21, terminal 21 and return wire 56. In order to break the circuit of the switches 19 and 21, the keys 13 and 17 are actuated and for changing the head lights of the automobile from dim to bright the push button 15 is operated. To connect the circuit in the main circuit the push buttons 2, 8, 10, and 11, are operated which, in turn, displace the combination locking tumblers 2., 8", 10", and 11, as indicated in Figs. 2 and 4, thus allowing the lugs 31 of the main circuit closing switch 36 to pass through the notch 66 in the combination tumblers 2, 8", 10, and 11", so that the main circuit closing switch can be moved in the direction of the arrow by the spring until the head 32 comes in contact with the terminals 39 thus completing the main circuit. In order to break the main circuit the main push button C is actuated which displaces the main circuit closing switch until the head 32 comes in contact with the terminals 38 whereupon the combi nation locking tumblers 2, 8", 10", 11", are returned to normal position by the springs 52. In Figs. 2 and 4 the combination locking tumblers 2", 8", and 11", are shown as they will appear when the correct combination is worked.

If one of the wrong combination locking tumblers is actuated, as indicated at 9", Fig. 3, it will engage the extension l5 of the alarm circuit closing key l i, thus forcing the key toward the back metal plate 4:3 and closing the alarm circuit between the front metal plate 41 and the back metal plate l3. The circuit will remain closed causing the alarm to sound continuously until the cor rect combination is operated and the main circuit closing switch is moved in the direction of the arrow. By virtue of the ratched notches 29 and the main circuit clos ing switch the circuit closing keys it are moved laterally and upwardly away from the back metal plate l3, whereby the alarm circuitclosing key Jelis forced into the position indicated in 2 and -l-. In Fig. 3 the lower key it bridges the gap 67 between the metal plates el l and thus closing the alarm circuit. Assuming that the combination is to be changed so that the push buttons 2, 3, 10, and 11, should not serve as releasing the longitudinal movement oil the main circuit closing switch, the appertaining combination locking tumblers 2-, 8, l0", and 11, are removed and re versed so that the notches 66 are turned toward the guide plates l7 and i7, as is shown at 3, :3, and 9, in Figs. :2 and The combination shall then comprise, for instance, the push buttons 3, 5, and 9, by turning the combination locking tumblers 3", 5, and 9, so that their notches (36 will be turned toward the filling plates 24-. and 25, as shown at 2", S, and 11", in Jigs. 2 and i. The cover B, of course, must be removed before the combination can be changed.

In applying my invention to an automo bile I attach it to the dash board A by means oi. bolts 26 after holes have been drilled in the dash board for the passage of the electric wires. .in electric signal bell is placed under the cover. or hood, of the engine where it cannot be reached from the outside ol? the hood.
